Metadata driven REST (representational state transfer) style application development method and system

Abstract

The invention discloses a metadata driven REST (representational state transfer) style application development method and a metadata driven REST style application development system. In the method, through analyzing a business service by using a model converter, and converting the business service into a RMF (remote management facility) based resource model, reading the resource model and generating a corresponding code framework, a client tool, a test case framework, a user interface template and an API (application program interface) document of a REST service, forming a system test case, and perfecting an implementation code of the REST service until the system test case passes, the universality of the REST service is realized, thereby expanding the application scope of the REST service. The system comprises a resource metadata framework, a model converter, a code generator and a service engine; through a unified metadata management framework, the definition of the REST service is standardized, and the consistency and maintainability of the service are improved; and through carrying out abstraction on the metadata of the REST service and following a popular programming style, the system is easy to be learned and grasped by developers, so that the reusability and automation degree of the system are improved, and the development process of modern agile software can be effectively supported.

Description

technical field [0001] The invention relates to a model-driven software development technology applicable to a REST-style SOA system architecture, in particular to a metadata-driven REST-style application development method and system. Background technique [0002] Representational State Transfer (REST for short) is a software architectural style proposed by Dr. Roy Fielding in his doctoral dissertation in 2000. Because REST-style web services are obviously more concise than complex SOAP and XML-RPC, more and more web services are beginning to be designed and implemented in REST style. Although some REST-style application development technologies and standards (such as JAX-RS, Restlet, WSDL 2.0, WADL, etc.) have emerged in recent years, there is still a lack of systematic methods and tools, and the development efficiency of REST-style applications is low. poor reusability. [0003] Major issues in RESTful application development today include: [0004] (1) There is no for...

AI Technical Summary

Problems solved by technology

[0004] (1) There is no formal specification for the definition of REST services. With the growth of software, it is difficult to maintain the consistency of API

Existing standards (such as WSDL 2.0, WADL) rely on XML, and development tools are relatively limited

[0005] (2) REST service programming styles are diverse, and the cost of learning and maintenance is high

[0006] (3) Lack of systematic tools and methods to support the entire process of software design, coding, testing, and documentation, especially unable to meet the needs of the modern agile software development process
